SCREAMER. 11 



clear cry, day and night ; that of the male like the word Chaja, of 

 the female Chajali, repeated alternately ; sometimes seen in pairs, at 

 others in flocks; and both male and female are alike; wades in the 

 water like the Heron, but does not swim, as it is only for the weeds 

 it can collect, for it neither eats fish nor reptiles. It is a tame 

 species, and may be domesticated like other poultry. 



M. Sonnini, the commentator on Azara, in a note says, he thinks 

 this to be different from the Horned Screamer, especially as it has 

 no horn. This seems very probable, especially as it is a much 

 smaller bird, the one here described being nine inches shorter ; nor 

 does it seem to answer in the colours of the plumage.
